Changes/features since 2.8.1a:- Restored Direct3D renderer.- Fixed sky scaling in low detail modes.- Added video menu options to switch between d3d and ddraw and set ddraw display bits for compatibility.- Usernames for ini files are back on win2k and later.- Proper startup banner modification.- More engine defaults changed for performance.- Some more official fixes.- Now compiled for pentium ii architecture but there's no performance difference.

Changes/features since 2.8.1:- Includes later fixes from the maint branch and some more.- Compiled with pentium architecture optimizations.- Low detail modes have been restored. Added a new quad horizontally and double vertically mode for a somewhat retrolook, you can get the original low detal mode from 640 and it's playable even @320. Unfortunately it gives the sameperformance as doubling horizontally and vertically.- A more retro looking startup console.- Engine defaults changed for slower machines.- Runs on windows 95 but without the startup log.- No direct3d nor xinput joystick support, only classic directdraw mode.- Uses a modified openal compatible with windows 95 as sound backend.- Compiled without fmodex support but should work, it's untested though. Fluidsynth doesn't work with openal andcould even crash on certain machines so no fluidsynth support either.- Hardware midi doesn't work on modern windows versions, it does on win9x.(*)- If you experience sound problems on very slow machines try reducing the sound channels to 8.- To set the default video mode on pentiums sometimes you need to press enter twice.

Changes/features since 2.1.4 CL R2:- Included old OpenGL renderer from GZDoom 1.0.17 with later fixes (off by default).- Added Skulltag's HQ resize options and texture compression.- Added sprite billboard options from GZDoom 1.0.31.- Autoloading of lights.wad.- Added early Direct3D renderer and a display menu option to switch between d3d and ddraw.- More modern default keyboard layout.- Command versions of the original Doom cheats.- Added buddha cheat.- Render cull options (sprite and wall distance) to increase performance.- More ZDoom patches (mostly up to date with ZDoom 2.1.5).- Now compiled for pentium architecture (but i guess performance on 486s will not be affected).

Changes/features since 2.1.4 CL:- Added video menu options to change fullscreen display bits for compatibility and disable widescreen aspectratio correction.- Forgot to disable decals by default for better performance.- Some more official fixes.

Changes/features since 2.1.4:- Includes some later fixes.- Compiled for 486 architecture.- Added a new quad horizontally and double vertically mode from ZDoom LE.- Added pixel doubled and quadrupled lowres directdraw modes from ZDoom 2.3 for more recent Windows versions.- Engine defaults changed for 486 machines.- Added some missing video settings to the display options menu.- To set the default video mode on slow machines sometimes you need to press enter twice.

Minimum estimated system requirements are: 486DX4-100, 16 mb of ram, 1 mb svga card and windows 95.Tested on a Pentium 90 with 32 mb of ram and a trident 1 mb graphics card on win95c, i get 38 fps @320x200.This is intended for vanilla levels and old mods from 2006.

NOTE: On windows 8 and above trying to go fullscreen on some systems when using ddraw you may get a black screen,a batch file (RUNME_WIN8_1ST.cmd) is included for convenience.A DirectDraw to OpenGL wrapper such as DXGL for GL 3 cards should fix the problem.
